a tank having a vertical vaxia which preferably flowyout through of the, invention will broken' away will be large "enough to hold aboutfrve gallons of fuel oil or a mixture of fuel oii'a'nd gasoline with a suitable air spaee therein above the oil,

The tank isfilled to the level indicated. "On top of this tank is provided a ian casing or housing 2 in which is mounted a rotary'or centrifugal fan or pump 3.; The bottom of the fan casing is open and the fan casing inclosesfl asimilar opening 13 inthe top of the tank 1 so that the -fan can blow "airior'a" mixture cfair and oil down through this opening'into the tank. The

fan is mounted on a horizontal shaft 4 and is driven'by a motor or 'pu1ley,'as mayirbe' desired. The shaft 4 is packed with a suitable-stuffing box to prevent the leaking of air either inor out; t r V I V In the side ofthe fanbasing is an intake-opening which is locatedcentrally with regard to the axis of the shaft of the fan. 'Into this opening is threaded a pipe 5', which extendslaterallyjirom the fan casingto an elbow and T joint 6. From this joint extends laterally'e oheck valve '1 and downwardly a pipe 8 whichpipepasses'intothe almost thereto, and'is serrated on the, bottom so" If} the liquid issuiii cientlyyolatile} the: pipe 3 1'isisfil fi mi r ith a "through the; A

-As shown in Figure 4, a tank 1' is providedon top of 'which is provided a fan casing 25, in which a fan is located similar to that shown inFigure 1. Into this fan casingis' drawn "a mixtureof air and oil from the tank-below, just the same as is shown inFigure-l. The fan casin'gjhowever, does not open into the tank; but discharges into a a conduit 26, through which the mixture 'of 'air and oil is conveyed to the point where it-is' to be used. Asshown in Figure 4, an air intakepipe 27. is provided which is controlled by avalve 28, .in 'theztanlz and the air supply that is needed is indicated in each case by arrows It will be understood that the term oil as used in the specification and claims of this patent means any liquid that is combustible in itself or that is capable of producing a gas or vapor that will burn.
